They eat small prey including frogs, lizards, birds and rodents. These snakes are either solid-toothed and non-venomous or rear-fanged and weakly venomous. Some of these species are arboreal while others favour semi-aquatic habitats. This family includes a small group of snakes with a range of specialised characteristics and habits. Non-venomous and rear-fanged venomous snakes (family Colubridae) This species grows to an average length of 0.4m. A similar species, the dwarf crowned snake, has a thinner white band around the top of the head and is slightly shorter in length (0.35m). It inhabits compost heaps and damp areas of gardens. It is considered to be one of the most common snakes in Brisbane, even occurring in the inner city. The crown surrounds the black scales on the top of the head. The white-crowned snake is dark grey above, with a light grey belly and a broad white band across the neck, sweeping forward around the side of the head and across the snout, creating the ‘crown’. Warning: Venomous. Not dangerous to humans These snakes are known to feed on small mammals, birds, reptiles (including other snakes) and amphibians. The venom injected by these snakes is used to immobilise or kill prey-sometimes a combination of toxic venom and constriction is used. Although this encompasses the highly venomous snakes of Australia, the venom of most species is harmless to humans. This family includes front-fanged, venomous land snakes. Front-fanged venomous snakes (family Elapidae) Of these snakes only the eastern brown snake is regularly found in Brisbane's suburbs. It is important to note that a number of venomous snakes are found in and around Brisbane, including the coastal taipan, tiger snake, death adder, rough-scaled snake and eastern brown snake. The most commonly encountered species are the carpet python, common tree snake, keelback, yellow-faced whip snake, white-crowned snake and eastern small-eyed snake. Some snakes can be found in suburban backyards and even in the city centre. The combination of native habitat and the introduction of exotic animals have influenced the distribution of some species of snake.
